We had our 14yo pit mix euthanized a few weeks ago due to a tumor on her brain causing seizures and other healthy problems. While she was absolutely the best dog I've ever had and great with other animals and our lil boy (now 4yo almost 5yo). IDK if I'd have another one now. I'm well aware of what they are capable of, both the good (it is not uncommon for them to be companion dogs for lonely elderly people) and the bad (can kill kids) and it just isn't worth even a super small risk to have a dog that might maul or kill my baby (the current child and the one we're pregnant with). I'd never forgive myself if I allowed that to happen "on my watch". We still have two bigger dogs; a border collie mixed with something tall and athletic and a pyrenese/aussie mix puppy thats not even a year old. Our pit mix was tiny, she was noticeably overweight at 40lbs. Both of the big dogs are good with other animals (both are actually submissive to other alpha/dominant animals, including our cat LOL), love people and are great with the kids (my wife also watches a 1yo baby).
